2 Claims.

My invention relates to improvements in paper rolls and mountings therefor, which are adapted for use in dispensing cabinets and other devices.

One of the difficulties encountered in dispensing paper from a roll when mounted in a disspenser is due to the fact that the paper having been put up in roll form develops a curl at its free end, which, if improperly directed when inserting the paper in the dispenser, will interfere or stop the free end of the paper strip from leading out to exposed position from the dispenser.

The present invention contemplates the provision of a roll and mandrel therefor which will make it impossible for the roll to be improperly inserted. Other advantages are that the roll may be produced without increase of cost over the conventional roll and that no difliculty or increase of cost is entailed in the packaging of said rolls in cartons or boxes.

The invention consists of a paper roll having a hollow core and a mandrel so mated that the roll can be carried by the mandrel when applied in one direction only, as will be more fully described in the following specification and shown in the accompanying drawing, in which:

Fig. l is a plan view of a dispenser cabinet showing the normal disposition of the paper roll.

Fig. 2 is a sectional view taken on the line 2-2 of Fig. 3.

Fig. 3 is a sectional view taken on the line 3--3 of Figure 2 showing the roll mounted upon its mandrel.

In the drawing like characters of reference indicate corresponding parts in each figure.

The dispenser cabinet here shown has side walls 2 and 3, a front door or wall 4 and a bottom wall 5, having a transverse slot 6 through which the free end of a paper roll is adapted to project for severance by any suitable means. Extending between the side walls 2 and 3 is a transverse paper guide I and below said guide is a roller 8.

Mounted along each side wall 2 and 3 are tracks 9 and both of which are spaced from their adjacent walls at the rear by brackets II. The track 9 is spaced and supported from the wall adjacent the front of the cabinet by a similar bracket [2 and the front end of the track I0 is supported on a resilient support [3 and is urged inwardly by a leaf spring I4 which bears upon the inner face of the wall 2. The tracks 9 and I0 consist of channels respectively numbered 15 and [5A, which channels are bordered above and below by a vertical wall [6 which bears lightly against an end of the paper roll. The channel 15 of the track 9 is relatively wide and the channel [5A of the track I0 is relatively narrow.

Adapted for mounting between the tracks 9 and I0 is a mandrel H, see Figure 2, having stub pivots l9 and I 8 which ride within the channels I 5 and [5A of the tracks 9 and Ill. The stub pivots obviously are of such transverse dimension as to fit the channels and thus insure the mandrel being inserted within its channels in the proper way. While the stub pivots are preferably circular in cross section to turn within their channels, it may in some cases be desirable that they be rectangular to prevent the mandrel from rotating, in which case the paper roll would rotate upon the mandrel. The mandrel I1 is divided into two portions 2| and 22, the portion 22 being of greated diameter than the portion 2|.

The paper roll generally indicated by the numeral 24 consists of a strip 25 wound upon a tubular core 26 of any suitable material, which core terminates short of one end of the roll, so as to accommodate the larger diameter portion 22 of the mandrel I1. It will be obvious that the paper roll can only be applied to the mandrel in one way, viz. by moving it to the right as seen in Figure 2 and that the mandrel can only be inserted into the cabinet in one way also, consequently the curl of the free end of the strip 25 will lead at all times in the direction intended, such as through the slot 6.

What I claim as my invention is:

1. The combination with a mandrel having cylindrical portions at opposite ends of different diameters, a paper roll having a disposable tubular core upon which the paper is wound, said tubular core being less in length than the paper rolled upon it, one of the cylindrical portions of the mandrel being of a diameter to fit within the tubular core and the other cylindrical portion being of a diameter to fit within the inner periphery of the paper rolled upon said core, that portion of the mandrel which is of the lesser diameter to be disposed within the core and the larger diameter portion of saidmandrel to be disposed within the paper roll beyond said core.

2. In combination with a paper roll, a mandrel having a stub pivot at each end and being circular in cross section, said paper roll having a hollow core upon which the paper is wound and which is of lesser length than the paper roll, said core extending from a point remote from one end of the paper roll to substantially the opposite end thereof, and said mandrel being of diameters to fit within the core and that portion of .the paper roll which extends beyond the remote end of the core, that portion of the mandrel which is of lesser diameter to be disposed within yond said core.
